Constrained Shape Analysis with Applications to RNA Structure
Kanti V. Mardia, Benjamin Eltzner, Stephan F. Huckemann
In many applications of shape analysis, lengths between some landmarks are constrained. For instance, biomolecules often have some bond lengths and some bond angles constrained, an…
Exploring Uniform Finite Sample Stickiness
Susanne Ulmer, Do Tran Van, Stephan F. Huckemann
It is well known, that Fréchet means on non-Euclidean spaces may exhibit nonstandard asymptotic rates depending on curvature. Even for distributions featuring standard asymptotic r…
Characteristic and Necessary Minutiae in Fingerprints
Johannes Wieditz, Yvo Pokern, Dominic Schuhmacher +1
Fingerprints feature a ridge pattern with moderately varying ridge frequency (RF), following an orientation field (OF), which usually features some singularities. Additionally at s…
Finite Sample Smeariness of Fréchet Means and Application to Climate
Shayan Hundrieser, Benjamin Eltzner, Stephan F. Huckemann
Fréchet means on non-Euclidean spaces may exhibit nonstandard asymptotic rates rendering quantile-based asymptotic inference inapplicable. We show here that this affects, among oth…
Confidence Tubes for Curves on SO(3) and Identification of Subject-Specific Gait Change after Kneeling
Fabian J. E. Telschow, Michael R. Pierrynowski, Stephan F. Huckemann
In order to identify changes of gait patterns, e.g. due to prolonged occupational kneeling, which is believed to be major risk factor, among others, for the development of knee ost…
Small sphere distributions for directional data with application to medical imaging
Byungwon Kim, Stephan Huckemann, Jörn Schulz +1
We propose new small-sphere distributional families for modeling multivariate directional data on for and . In a special case of univariat…
